Silicon Metal The Quartz Corp High Purity Quartz

Silicon Metal. The most common method of silicon metal production is through a metallurgical process. This process begins with a lump of quartz of medium to low purity mixed with carbon, which then goes through several cleaning steps to be processed into higher grades. This silicon metal can then be used for silicon crystals,

Production. Typical crystalline silicon solar cells are produced from monocrystalline (single-crystal) silicon or multicrystalline silicon. Monocrystalline cells are produced from pseudo-square silicon wafers, substrates cut from boules grown by the Czochralski process, the float-zone technique, ribbon growth, or other emerging techniques.
